# `MingaEditor.Renderer.Caches`
[🔗](https://github.com/jsmestad/minga/blob/main/lib/minga_editor/renderer/caches.ex#L1)

Explicit render-pipeline cache state, replacing process-dictionary entries.

Each field corresponds to a former `Process.put/get` key used across the
render pipeline stages. The struct is carried on `EditorState` and on
`RenderPipeline.Input`, survives across frames, and is written back via
`EditorState.apply_render_output/2` after each pipeline run.

## Ownership by stage

- **Chrome** (`chrome_prev_*`): `RenderPipeline` — stage 5 fingerprint cache.
- **Content** (`search_decoration_cache`, `doc_highlight_cache`): consumed by
  `ContentHelpers.build_render_ctx/3`; cleared when the fingerprint changes.
  `block_render_cache` is a within-frame cache reset after each window render.
- **Emit** (`emit_prev_*`, `last_title`, `last_window_bg`):
  consumed by `Frontend.Emit` stage 7.
- **GUI chrome** (`last_gui_*`): fingerprint caches inside `Emit.GUI`.
